Automatic Journey Re-planning for Passengers in the Case of Incidents

Current passenger information services and mobile applications aim much more at casual passengers than at commuters. In particular, in the case of delays and incidents the support to affected passengers is not satisfactory. In contrast, the personalised information services pVID and PIEPSER offer operational alternatives to a passenger if his journey is affected by an incident or delay. However, the alternative journeys must have been specified before. The better solution is to perform a journey re-planning automatically if an incident or delay occurs. The paper presents problems and solutions regarding this context. The described function of automatic journey re-planning has been integrated into an information service and was recently being tested.
